Amifirm
by Amihai Antebi
We build software and we secure it. Senior, AI-assisted engineering and application security.
We combine hands-on architecture, secure code review, threat modeling, and cross-checking across leading LLMs and AI models to reduce real-world risk before release.
Build, end-to-end
Full-stack web, mobile, and AI products, from architecture to production. Built for the real world, not just demos.
Right-sized security
Application security with a clear scope: threat modeling, secure code review, penetration testing, and remediation. Not a SOC, not an MSSP, and no enterprise overkill.
Engineers + AI, combined
Senior engineers use multiple AI models as review assistants, then validate the results manually to catch design, code, and configuration risks a single tool can miss.
Senior and hands-on
The person you hire is the person who does the work. 21+ years, ex-Matrix, 7 enterprise systems across finance and government.

Selected Projects
Real products built end-to-end, from architecture to production.
PhrasiGo
A language learning app supporting 40+ languages with spaced repetition, quizzes, and native audio. Built end-to-end as a solo project. Available on Android; iOS planned.
Enterprise Systems (Matrix)
Led development of 7 large-scale enterprise systems across finance and government sectors. Owned architecture and key technical decisions for complex, high-impact production systems.
Computer Vision & ML
Facial keypoint detection using CNN and OpenCV. Pre-processing pipeline with de-noising and edge detection. Achieved 0.83 validation accuracy.
Let's build something production-ready. And keep it secure.
Whether you're building something new, scaling an existing system, or hardening what you already run, Amifirm can help you move it forward.
